PICK TAKE-UP SHUTTLE.

Specification of Letters Patent.

Patented May 4, 1920.

Application led January 8, 1918. Serial No. 210,915.

' Pick Take-Up Shuttles; and I do hereby declare the following to be alV full, clear, and exact description. of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a pick take up shuttle for looms.

The object of the present invention is to provide a simple, practical and eflicient'shuttle of strong, durable and comparatively inexpensive construction adapted to be placed in a loom and substituted for an ordinary weaving shuttle for unweaving the cloth or other fabric to take up the filling of a pickout or bad spot in the cloth thereby effecting a saving of time and labor in removing such bad spot due to a defective weaving of the cloth. A further object of the invention is to provide a shuttle of this character adapted to save the filling removed'from the cloth and enable'the filling to befreused so that the filling removed from a pickout or bad spot will not be wasted.

Another object of the invention is to pro- `vide a shuttle of this character' adapted to maintain a uniform tension on the thread or filling and capable of enabling the tension to be readily adjusted as required.

With theseand other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that va- Arious changes in the form, proportiomsize and minor vdetails of construction, within the scope ofthe claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.

In the drawing:

' In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the shuttle comprises in its construction a reel 1 located within a shuttle body l'a of the ordinary form adapted to be `substituted for an ordinary `shuttle in a loom and to work back and forth in the loom raceway 1b in the same manner as an ordinary weaving shuttle. Thev shuttle body carries a plunger 2 slidably mounted in a sleeve 3 and normally maintained in a projecting position by a spring 4 disposed on the plunger and interposed between a shoulder 5 and screws 6 extending inwardly from opposite sides of the shuttle body and `forming stops for the inner end of the coiled spring. At the end of each trip the plunger is forced inwardly against the action of the coiled'spring 4, and it is provided at its inner end with a curved arm 7 carrying a pivoted pawl 8 which is maintained in its engaging position by a spring 9. The spring 9 is secured at one end to the arm 7 and its other end is free and bears against the pivoted pawl 8. The ratchet wheel 10 is mounted on a winding shaft 11 and it is engaged by the pivoted pawl 8 which rotates the ratchet wheel on the inward move ment of 'the plunger and which ratchets over the teeth on the outward movement of the plunger so that the winding shaft is rotated a portion of a revolution at eachjinward Vmovement of the plunger.

The winding shaft is connectedto the inner end 12 of a spiral spring 13 having its outer end 14 secured to a gear wheell constituting the first gear of a train of gears for transmitting motion from the spiral spring to the reel l. The train of gears comprises the said gear wheel 15` Aa pinion 16 'mountedon a counter shaft 17 which also carries a gear wheel 18f that meshes with a pinion 19 of the shaft 2() upon which the reel is mounted. The train of gears is adapted to increase and multiply the speed, and the gears may he of any desired ,dimensions to secure the desired ratio of speed between the spool or reel shaft 2O and the winding shaft. l

The'parts will be Aproportioned so that the rewinding of the spring or the intermittent winding of the spring will rewind at the end of each trip the amount ofspring un- Wound during the trip so that the mecha-l nism will be maintained under practically uniform tension, and the'tension may be adj usted by rotating Winding shaft 11 through the medium of a key of usual type for adjusting the tension of the spiral spring. In order to prevent the spring from unwinding at the end of the stroke and the reel from rotating when notpicking up or gathering v at one end at 23 and connected at a point adjacent to its other end with a rod 241. The rod 24 is also connected with the brake spring. The lever, which presents an outer Y convex face, is adapted at the end of a stroke to be 'forced inwardly through contact with Y the usual brake spring 241a ofthe raceway 1b, and when the lever is forced inwardly,

the spring will be caused to bear against the reel and stop the motion of the same so that there will be no free rotation of the reel when the shuttle is at rest. When the shut tle starts to move, the reel Will be released and will be permitted to perform its function in taking up the filling. The shuttle body is preferably equipped with a casingY 25 composed of a bottom and sides and provided vvith cross bars 26, the shafts being mounted in the cross bars and the bottom of the casing 25, but any other suitable means may of course be employed for supporting the gearing.

The shuttle, which is adapted to take the place of an ordinary shuttle, moves back and forth across the loom and takes up the filling on Vthe spool or reel unvveaving enough of the cloth to correct a bad place. The shuttle will save time and labor and material and will obviate the necessity of employing the relatively large number of hands usually employed about a mill for attending to pickouts or unweaving. Any suitable means may be employed for enabling the spool or reel to be placed on and removed' from the shaft on which it is mounted so that when the reel is full an empty one may be substituted for it.

The ratchet Wheel 10 is held against retrograde rotation by a check pawl 27 pivoted -at 28 andmaintained in engagement with the ratchet wheel by a spring V29. As the shuttle is moved out of the end portion of the raceway brake lever 22 is released thus permitting rotation of thereel in a winding direction during travel of the shuttle lacrossthe loom so as to wind the thread onto the same.` As the shuttle enters the other' end of the raceway, brake lever 22 en yratchet Wheel 10 and pawl S, thisrotation of the winding shaft serving to rewind the spiral spring 13 an amount corresponding tothe extent to which 'this spring was unwound during passage of the shuttle across the loom for rotating the reel in Winding direction. In this-manner, the spring 13 is utilized as a medium for storing the energy generated by movement of the shuttle, this energy beingrutili'zedrfor rotating the reel for Winding the thread thereon.

It will be understood, of course, that gear wheel 15 is mounted upon winding shaft 11 forindependent rotation about they same,

,this gear wheel, which constitutes the main drive Wheel of the gear train, serving to rof tate the reelrin winding direction. When the shuttle is in the end portion of the raceway, the reel is locked against rotation as in Fig. 1 thus locking gear lagainst rotation, winding shaft 11 being rotatable under the iniiuence of pawl 8 and the plungerV associated therewith in winding direction upon the'plunger 2 being struck and forced'inwardly for driving the shuttle alongthe raceway across the loom.
